Period 7,8
1. Effective Collisions – as per the diagram.
Every chemical reaction requires collision that are effective = Effective Collisions
effective collisions require 2 things:
1. Energy to overcome repulsive forces of electrons (that are on the outside of the molecules) . ELECTRONS FROM ONE REACTANT REPELS THE ELECTRONS FROM THE OTHER SINCE ELECTRONS ARE NEGATIVE AND LIKE CHARGES REPEL.
Thus as two reacting molecules start to collide they start to repel until they reach a maximum energy of repulsion = peak energy = Activated Complex. The energy needed to overcome the activated complex peak is called Activation Energy (Ea).
Every chemical reaction exergonic or endergonic must overcome the energy barrier with Ea.
2. Molecules have to collide in areas that can bond and not in area that it cannot. Thus molecules must collide with the correct orientation ALONG with Ea.
1: Light stick Demo – proved the collision theory of molecules.
2. Nitrogen (l) / balloon – proved motion of gas molecules
3. Rate of reaction – Rate of metabolism Demo – Radio
In all 3 demonstrations Energy is being driven from a system spontaneously by the coupling of a spontaneous process (boiling of the liquid nitrogen) with a non-spontaneous process.
2. Review the Notes with Gummy Bear Demo.
Relate it to Biological Metabolism:
4. Coupled process —–> into Biological reactions.
Exergonic = catabolic —–> Endergonic – anabolic
breaking down Driven building big molecules
glucose making enzymes
** The ΔG must be negative enough to drive the positive Endergonic process!
5. Complete the notes for the Whoosh and the Cool reaction.
Cool reaction demo!
Cool Uplifting Chemical Reaction Demo:
today’s Period 7 lesson:
2/3 – Wednesday – Homework :
1. Be spontaneous ! Ride the pony! Do not carry the Pony up the hill!
2. Make another submission to your MC sections of your genetics Test.
I will give the the average of the 2 submissions. I will send out the 1st graded submission this afternoon AND I will provide the links below to the 2 forms.
Use the links below to redo the multiple choice. There is no timer and no auto-reply.
Genetics Test – Multiple Choice – A – https://forms.gle/xJvHj1roQCdAoXoi8
Genetics Test – Multiple Choice – B – https://forms.gle/HkmTszmXWfR4NC318
3. Resubmit the Form from this weekend:
This weekend form:
I will have it on auto- reply so you can study for tomorrow’s extra credit Energy “test”.
End of Wednesday..
2/4 – Thursday – “B” Day –period 7B, 8B– I 7(B) 8(B,D) AP BIOLOGY – (double period Lab)
-period 7B, 8B -R 7(B) 8(B,D) AP BIOLOGY – REMOTE INSTR
The Blue team is remote today. Please move to the Remote Instruction page.
1. Extra Credit Form:
2. Review of Cool Uplifting demo yesterday:
3. Introduction of Gibbs Free Energy equation:
Always Rule, Never Rule, Sometimes Rule
4. Solidification (hand warmer) demo Reviewed – started.
Gibbs free Energy and Entropy Notes key – page 6.pdf
The Entropy ΔSuniverse is affected by two factors
There are two ways that energy can be “dispersed” or released.
1. Heat or thermal energy is released into the surroundings. ΔH = heat of reaction
This thermal energy will increase the temperature of the surroundings and increase the motion of
surrounding molecules. This increased motion will make these surrounding molecules “move away”
and disperse their motion energy “away” from the system.
ΔH = negative if HEAT energy is released – (increases ΔSuniverse )
ΔH = positive if HEAT energy is absorbed – (decreases ΔSuniverse )
2. The degrees of freedom of the particles or molecules increases. ΔS = entropy of particles
The chemical reaction or physical process increases the number of moving “parts” so that motion
energy is dispersed as the chemical or physical process proceeds.
ΔS = positive if degree of freedom increases for molecules as process proceeds.
ΔS = negative if degree of freedom decreases for molecules as process proceeds.
To measure a if the Entropy ΔSuniverse is decreasing or increasing we use Gibbs Free Energy Formula:
ΔG = ΔH – TΔS
IF ΔG = negative then the Entropy ΔSuniverse is increasing = Spontaneous
IF ΔG = positive then the Entropy ΔSuniverse is decreasing = Non – Spontaneous
2/4 – Thursday – “B” Day Homework:
1. Please view the signs lecture and take notes.
2. Complete the Thermo signs lecture.
End of Thursday!
2/5 – Friday – “C” Day – period 7C, 8C -I 7(C) 8(A,C) AP BIOLOGY – (double period Lab)
– period 7C, 8C –R 7(C) 8(A,C) AP BIOLOGY – REMOTE INSTR
The RED Team is REMOTE again &^$(&&(&%%#%#!!!!!
1. Reviewed the Always Rule, Never Rule, and Sometimes Rule in the Gibbs Free Energy Equation
2. Review of Gummi Bear demo – without ΔH and ΔS values.
*Look at the always rule of the combustion reaction of propane (torch). Explain why not all Free Energy is transferred from one process to another. This is important in ecology as the producers have the greatest
amount of energy in an ecosystem.
3. Review of Cool demo with values.
4. Solidification (hand warmer) demo Reviewed.
Today’sClass Whiteboard:
Cool Reaction: What is spontaneous and what is non-spontaneous is this demo?
The Entropy ΔSuniverse is affected by two factors
There are two ways that energy can be “dispersed” or released.
1. Heat or thermal energy is released into the surroundings. ΔH = heat of reaction
This thermal energy will increase the temperature of the surroundings and increase the motion of
surrounding molecules. This increased motion will make these surrounding molecules “move away”

2. The degrees of freedom of the particles or molecules increases. ΔS = entropy of particles
The chemical reaction or physical process increases the number of moving “parts” so that motion
energy is dispersed as the chemical or physical process proceeds.
ΔS = positive if degree of freedom increases for molecules as process proceeds.
ΔS = negative if degree of freedom decreases for molecules as process proceeds.
To measure a if the Entropy ΔSuniverse is decreasing or increasing we use Gibbs Free Energy Formula:
ΔG = ΔH – TΔS
IF ΔG = negative then the Entropy ΔSuniverse is increasing = Spontaneous
IF ΔG = positive then the Entropy ΔSuniverse is decreasing = Non – Spontaneous
Hand warmer demo: Is this spontaneous? Why must heat be given off in order to for this solution to become a solid? When has this physical process reached equilibrium?
Today’s Lesson:
2/5 Friday Homework –
1. Make another submission to last nights Form -after today’s lesson!
2. Read me! Look at the 2 reactions below. The first reaction is the phosphorylation of glucose which is required in the 1st step to get Free Energy out of the glucose. As you can see the first reaction is not spontaneous (ΔG is not negative!) and it is the driven by the second reaction that is spontaneous (ΔG is negative). In this coupled process the the overall ΔG is -17 to show that the spontaneous reaction of ATP was spontaneous enough to DRIVE the first reaction. You may have learned that ATP is the energy currency of the body AND THE reason it is needed by all life sustaining chemical reactions is to COUPLE the endergonic reactions of life that require a steady supply of Free Energy. We will learn that we get ATP from the breakdown of glucose in our body (cellular respiration).
3. Complete ATP worksheet with textbook (Chapter 8).
3. Review with the key – There are mistakes in my key. Question 1 b should have 2 phosphates NOT 3 and 7b should be Exergonic NOT Endergonic! I feel bad and I am over it.
